A Review on Thermal and Structural Analysis of Disc Brakes in Motor Vehicles
Abstract: Braking is a technique that turns kinetic energy in a vehicle into mechanical energy that must be dissipated as heat. The frictional heat created at the disc-pad interface can cause high temperatures during the braking period. Thermal elastic instability (TEI), early wear, brake fluid vaporisation (BFV), and thermally stimulated vibrations can all be caused by frictional heat created on the rotor surface (TEV). In this research, a vehicle's solid type …

Synthesis and Characterization of Graphene-Based Hydroxyapatite Using Hydrothermal Method for Its Biomedical Application
Abstract: Developing bone implant materials that combine biological compatibility with mechanical strength remains a major challenge in orthopedic research. Hydroxyapatite (HAp) closely mimics bone mineral and supports cell growth, but its brittleness limits load-bearing applications. To address this, a quaternary nanocomposite of hydroxyapatite (HAp), graphene (Gr), zirconia (ZrO2), and ferrocene (Fc) (Hap-Gr-ZrO₂-Fc) was synthesized through a one-step hydrothermal process. Graphene and zirconia provided reinforcement, while ferrocene contributed structural stability and carbon …
